Simulation study on the transmission characteristics of Laguerre-Gaussian beams with different orders in smoke channels

Le résumé fourni par la source

Laguerre–Gaussian (LG) beams carrying orbital angular momentum (OAM) are promising for atmospheric and underwater optical transmission. In this work, based on generalized Mie scattering theory, the relationship of the electric field before and after photon scattering is derived, and the Electric Field Monte Carlo (EMC) method is applied to simulate LG beam transmission in smoke channels. The effects of topological charge, radial index, and propagation distance on scattering and transmission are analyzed. Results show that higher-order beams are more vulnerable to scattering, leading to stronger attenuation and phase distortion. This study provides theoretical guidance for modeling and optimizing OAM beam transmission in complex particulate media.
